Best MPC Wallets 2026: Vultisig vs Zengo, Fireblocks & More

Think of an MPC wallet as a safe that only opens when two keyholders turn their keys together. Nobody ever holds the whole combination, so there's no single thing to steal. That's multi-party computation: your private key is created in pieces, each piece lives in a different place, and a threshold of them signs every transaction.

No seed phrase to steal. No single device that can drain you.

Every MPC wallet works that way. What separates them is one question: who holds the other pieces? Your devices, the company's servers, or both. Get that answer right and the rest follows.

This guide compares the best MPC wallets of 2026 on the things that decide that answer, plus the details you'll live with every day:

• Who holds the key shares
• Whether the company co-signs every transaction
• Open source
• Recovery, including what happens if the company disappears
• Chains, platforms and price

Facts were checked against each wallet's own documentation and pricing pages in October 2026. Sources are linked throughout.

Seedless but not MPC: Tangem and Bitkey, covered at the end.

1. Vultisig: best overall MPC wallet for self-custody

Vultisig is the MPC wallet that hands you the keys, all of them if you want. It's free, open source, and signs with DKLS23 threshold signatures, using Silence Laboratories' implementation, which Trail of Bits audited. We run our own treasury on it.

• Who holds the shares. In a Secure Vault, every share sits on a device you own, from 2-of-2 to setups like 2-of-3 or 3-of-4. No server takes part. In a Fast Vault, your device holds one share and VultiServer holds the other; VultiServer co-signs but can never sign alone.
• Recovery that never depends on Vultisig. Each device exports its own backup file. In a Fast Vault, the server's share is emailed to you, encrypted with your password, so you hold everything needed to recover. If Vultisig's software ever became unavailable, the documented emergency recovery path rebuilds your key from your shares.
• Open source. The wallet code is public at github.com/vultisig.
• Chains. 36+ chains in one vault, including native Bitcoin, Ethereum, Solana, THORChain, XRP and Cosmos chains. See how one vault covers them.
• Platforms. iPhone, Android, macOS, Windows, Linux and a browser extension.
• Price. Free to use, with no subscription. Swaps carry a 0.50% fee, which drops to 0% for $VULT holders on the discount ladder.

Setup takes about a minute with a Fast Vault on one device. A Secure Vault takes a second device and puts every share in your hands. No seed phrase in either.

It's also built for what's next. The Vultisig SDK gives AI agents a self-custodial wallet, so automation can act on funds without anyone handing over a key.

Best for: anyone who wants institutional-grade MPC without a company in the signing loop, across every major chain.

2. Zengo: the best-known consumer MPC app

Zengo made MPC approachable for millions of people, and its onboarding is genuinely easy. eToro completed its acquisition of Zengo on April 30, 2026.

• Who holds the shares. Two shares: a Personal Share on your phone and a Remote Share on Zengo's servers. Both sign every transaction together (Zengo help).
• Recovery. Zengo's "3FA": your email, a recovery file in your cloud, and a 3D face scan. If Zengo ever shut down, it describes a recovery system run by independent escrow companies (Zengo help).
• Open source. Zengo's MPC libraries are public on GitHub.
• Chains. 14 blockchains, including Bitcoin, Ethereum, Solana and XRP (Zengo help).
• Platforms. iPhone and Android.
• Price. The wallet is free; Zengo Pro adds features through a paid subscription.

Best for: first-time crypto users on a phone. If you'd rather hold every share yourself, or need more chains, Vultisig's Secure Vault removes the server share entirely.

3. Fireblocks: the institutional standard

Fireblocks runs MPC for exchanges, banks and payment companies, and its policy engine is built for large teams moving serious volume.

• Who holds the shares. Three co-signers. By default, the customer holds one share and Fireblocks holds two in secure enclaves; all three are needed to sign (Fireblocks support).
• Recovery. A Workspace Key Backup, made offline, lets a customer rebuild the full key if Fireblocks suspends operations (Fireblocks support).
• Open source. Its MPC library (mpc-lib) and key recovery tool are public.
• Chains. 150 public blockchains (Fireblocks).
• Price. Essentials starts at $999 a month; custom plans start at $36,000 a year (pricing).

Best for: institutions with compliance teams and enterprise budgets. Individuals and smaller teams get the same threshold security from Vultisig, for free.

4. BitGo: institutional custody with an open recovery tool

BitGo has secured institutional crypto for over a decade and listed on the NYSE in January 2026.

• Who holds the shares. Three keys: yours, a backup key and BitGo's. Normal transactions use your key plus BitGo's (BitGo docs).
• Recovery. The open-source Wallet Recovery Wizard moves self-custody funds using your key and the backup key, without BitGo.
• Open source. The SDK and recovery tool are public.
• Coverage. Over 1,700 digital assets, including native Bitcoin.
• Price. Enterprise pricing through sales.

Best for: regulated institutions that want a custodian alongside self-custody. If you want the threshold model without the custodian, Vultisig gives it to you free.

5. Fordefi: institutional MPC built for DeFi

Fordefi focuses on trading firms and funds that live in DeFi, with transaction simulation and a browser extension for dApps. Paxos acquired Fordefi in November 2025.

• Who holds the shares. Each key is split between Fordefi, in a cloud enclave, and the customer's device or API signer (Fordefi docs).
• Recovery. A required organization key backup lets customers rebuild keys independently of Fordefi (Fordefi docs).
• Chains. Dozens of networks across EVM, Solana, Cosmos, Bitcoin and more (Fordefi docs).
• Price. Through sales and demos.

Best for: institutional DeFi desks. Vultisig brings native cross-chain swaps and dApp access through its browser extension to anyone, with no sales call.

6. Dfns: MPC infrastructure for builders

Dfns is wallet infrastructure rather than a consumer app: an API that banks and fintechs use to put MPC wallets inside their own products.

• Who holds the shares. In its hosted service, Dfns runs the signer network across data centers; users authorize with passkeys. Hybrid and on-premise setups let customers run signers themselves (Dfns docs).
• Recovery. Key export and a backup encrypted with the customer's own key.
• Open source. Its CGGMP21 protocol library is public through LFDT Lockness.
• Chains. 100+ networks.
• Price. From $800 a year (pricing).

Best for: developers building custody into their own product. Building a multi-chain app without holding keys yourself? The Vultisig SDK does that too.

Seedless, but not MPC: Tangem and Bitkey

Two popular wallets also skip the seed phrase, using different architecture.

• Tangem. A single private key generated inside a secure chip on an NFC card, backed up to two or three cards instead of a seed phrase. Supports 90 blockchains. A 2-card set costs $59.90.
• Bitkey. Block's Bitcoin-only 2-of-3 multisig. You hold the phone and hardware keys, Bitkey holds the third, and an Emergency Exit Kit moves funds without Bitkey (how it works). The device costs $250.

Both are strong picks for hardware lovers. Vultisig gets you seedless, multi-device security with the phones and laptops you already own, across 36+ chains.

A note on Coinbase Wallet

Coinbase Wallet (formerly the Base app) is often listed with MPC wallets, but none of its three wallet types is MPC: one uses a 12-word recovery phrase, one uses a passkey smart wallet, and one is an email login whose keys run in Coinbase infrastructure (Coinbase help). Its classic wallet closed on August 15, 2026, ending support for networks including Litecoin, Dogecoin and XRP. Vultisig supports all three natively, along with Bitcoin, Ethereum and Solana. See Vultisig vs Coinbase Wallet.

Which MPC wallet should you choose?

• You want every share on your own devices: Vultisig Secure Vault.
• You want one-minute setup with no seed phrase: Vultisig Fast Vault.
• You run an institution with a compliance team: Fireblocks, BitGo or Fordefi.
• You're building custody into a product: Dfns, or the Vultisig SDK.
• You only hold Bitcoin and want hardware: Bitkey.

For most people holding real money across more than one chain, Vultisig is the strongest setup: open source, free, 36+ chains, and a vault where you decide who holds the keys.

If it's good enough for our treasury, it's ready for yours.
